9. Ceftonit is an antibacterial medicinal product of the cephalosporins group.

10. Ceftiofur hydrochloride, an active substance of Ceftonit, is a third generation broad-spectrum cephalosporin antibiotic that has bactericidal effects on gram-negative and gram-positive bacteria, including ß-lactamase producing strains and some anaerobic bacteria: Escherichia coli, Pasteurella (Mannheimia) haemolytica, Pasteurella multocida, Haemophilus somnus, Actinobacillus pleuropneumoniae, Haemophilus parasuis, Salmonella cholerasuis, Streptococcus Suis, Streptococcus zooepidemicus, Streptococcus equi, Pasteurella spp., Staphilococcus spp., Actynomyces pyogenes, Salmonells typhimurium, Streptococcus agalactiae, S. dysgalactiae, S. bovis, Klebsiela, Citrobacter, Enterobacter, Bacillus spp., Proteus spp., Fusobacterium necrophorum and Porphiromonas assacharolytica (Bacteroides melaninogenicus).

Following parenteral administration, ceftiofur is rapidly metabolized to desfuroylceftiofur and reaches therapeutic concentration in the body within 1 hour; this concentration is maintained for 20 hours. Antibiotic is primarily excreted in the urine (more than 55%) and partly with faeces.
